Previous main lunar phase is the First Quarter before 2 days on 11 December 2021 at 01:36.
Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.
Moon is passing about ∠20° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1813" and ∠1949".
Next Full Moon is the Cold Moon of December 2021 after 5 days on 19 December 2021 at 04:36.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 9 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 271 of Meeus index or 1224 from Brown series.
Length of current 271 lunation is 29 days, 10 hours and 50 minutes. It is 23 minutes shorter than next lunation 272 length.
Length of current synodic month is 1 hour and 54 minutes shorter than the mean length of synodic month, but it is still 4 hours and 15 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠358.3°. At beginning of next synodic month true anomaly will be ∠13.9°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
9 days after point of perigee on 4 December 2021 at 10:01 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 4 days, until it get to the point of next apogee on 18 December 2021 at 02:16 in ♊ Gemini.
Moon is 395 364 km (245 668 mi) away from Earth on this date. Moon moves farther next 4 days until apogee, when Earth-Moon distance will reach 406 322 km (252 477 mi).
9 days after its descending node on 3 December 2021 at 14:58 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 17 December 2021 at 00:12 in ♊ Gemini.
23 days after beginning of current draconic month in ♉ Taurus, the Moon is moving from the second to the final part of it.
7 days after previous South standstill on 6 December 2021 at 02:25 in ♑ Capricorn, when Moon has reached southern declination of ∠-26.331°. Next 6 days the lunar orbit moves northward to face North declination of ∠26.306° in the next northern standstill on 20 December 2021 at 04:32 in ♋ Cancer.
After 5 days on 19 December 2021 at 04:36 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
